Definitions

  • the locking device therefore makes it possible to select in an appropriate manner, during a step of positioning the bone screw, the position and orientation of each bone screw with respect to the main direction of extension of the bone to be strengthened, that is, the arrangement of the locking element and the coupling element and therefore the configuration of the external fixator.
  • the stabilizing element 504 is an anti-rotation element.
  • the variation device 7 comprises a first part 8 fixed to the support unit 2 , a second part 9 fixed to the other support unit 2 ′, and a deformable element 10 interposed between the first part 8 and the second part 9 to allow said controlled variation.
